4. Watch: 5 facts about Density (stop at 2:40)
In your notebook copy this question
What makes the same substance more or less dense?
Does cutting something in half change its density?
As you watch the video record your answer.

5. Pair Share

6. Computer Simulation
We will now use the computers to practice with density using a computer simulation. Work with your partner on the simulation be sure to complete the density investigation worksheet on L/R.

8. Density
Which is Denser?

9. Watch: Density vs Temperature
In your notebook copy this question
How does Temperature affect the density of water and air?
As you watch the video record your answer.

10. Draw a model showing Hot Air and Cold Air
Be sure to describe and show
Temperature (Thermal energy)
Molecular movement (kinetic energy)
Molecular spacing (density)
Amount of molecules (mass)

11. Which state of matter is least dense? Most dense?
liquid
Solid
Gas
Molecules move very slowly! They are close together.
Molecules move faster and are more spread apart.
Molecules move very fast! They are very spread apart.
